| 摘 要： | 为了补偿惯性约束聚变（ICF）冷冻靶冷却过程中非球对称腔体的热流分布，通常在冷却的同时在腔外壁上施加辅助加热。在间接驱动靶中建立了1维热传导理论模型，分析所需辅助热流密度，同时在2维轴对称模型下，利用计算流体力学的FLUENT程序，对辅助加热机制进行了热力学模拟。当把辅助加热设在腔外壁的中平面上下各1.3 mm的范围时，得到了最佳辅助热流密度为635 W/m2，与理论结果基本一致。

| Abstract: | In order to compensate for the nonsphericalsymmetric heat flux in the hohlraum, auxiliary heating is usually applied to the outside wall of the hohlraum during the cooling process. A one-dimensional heat exchange theoretical model has been proposed in the indirect-drive target, to analyze the required auxiliary heat flux. With a two dimensional axi-symmetric model, the auxiliary heating mechanism has been simulated by FLUENT code. The optimum heat flux which is 635 Ｗ/m２ has been obtained as the heaters around the outside of the hohlraum about 1.3 mm above and below the mid-plane. The result is in good agreement with the theoretical model． |
